Command Line Interface

npm install -g

• -j, --json: output as json
• -c: output with no-color

Use as node module

$ npm install dts-parser

parser = require 'dts-parser'
console.log parser.parse('declare var x: number;')

Test

$ npm install
$ ./update-fixtures
$ npm test

test/parsed have generated json by ./update-fixtures from test/fixtures.

Tests compare pre-generated json to json generated by current parser.
